Is negative kinetic energy meta-stable?
Christian Gross, Alessandro Strumia, Daniele Teresi +1
We explore the possibility that theories with negative kinetic energy (ghosts) can be meta-stable up to cosmologically long times. In classical mechanics, ghosts undergo spontaneou…
Constructing de Sitter vacua in no-scale string models without uplifting
Laura Covi, Marta Gomez-Reino, Christian Gross +2
We develop a method for constructing metastable de Sitter vacua in N=1 supergravity models describing the no-scale volume moduli sector of Calabi-Yau string compactifications. We c…
Constraints on modular inflation in supergravity and string theory
Laura Covi, Marta Gomez-Reino, Christian Gross +3
We perform a general algebraic analysis on the possibility of realising slow-roll inflation in the moduli sector of string models. This problem turns out to be very closely related…
de Sitter vacua in no-scale supergravities and Calabi-Yau string models
Laura Covi, Marta Gomez-Reino, Christian Gross +3
We perform a general analysis on the possibility of obtaining metastable vacua with spontaneously broken N=1 supersymmetry and non-negative cosmological constant in the moduli sect…
